Hello all I just picked up a Time Warner DVR for my Mom. Its a SA 8300 running passport software. I am a Cox tech and tried to get into the diagnostic menu using the Cox buttons but it did not work. I was wondering if anyone could help me out with this. I also was wondering if there is a way to enable the AUX input on the box.

Sure it is. I'm using it right now. I have 2 SA 8300HDs from Time Warner running SARA and it's enabled on both. With the cable box on and the remote in cable mode I just hit the Video Source button and it takes me to Aux In on the front display it reads Au.

hey guys..... this is exactly what i was trying to figure out...... I'd like to utilize Aux inputs on TWC DVR (passport software???).... when I hit the video source button nothing happens..... what do I need to do????? Thanx!!!!
